provements in Looking Devices, of which the following is a specification.

. Our invention relates to hasp and staple devicessuch as areused chiefly on sliding doors. They are particularly useful on car doors. 1 The object ofour invent on s to produce such a device which shall be adapted to doors sliding either to the right or, left of their closed position, which shall be securable to the door andcasing, so. as to be practicably irremovable from without.

Further objects of our invention will appear in thisspecification and be po nted out in the claims. u u s In the drawings Figure l is a partial elevation of a casing and doorprovided with our invention, Fig. 2 is a. horizontal section- ;through the plane 2-2,,F1g. 1; Figs. 3

and 4 are enlarged perspective yiews of parts of the staple device; Figs. dand 6, 7 and 8, 9 and 10 are views similar to F gs. 3 and 4 but showing modificationaFig. 11 is a reversed elevationof thehasp portion of: the device shown in Fig. 1. Figs. 12 and 13 are partial elevations of details of the device i In the particular embodiment of our invention illustrated inFigs. 1, 2, 3, 4 and 11 .ofthe drawing, 21designates the s de or body of a car ,orother structure, 22 is a door sliding thereon by means of any well known or desired form of hanger, not/shown; 23 is a vertical post on casing 21 againstjwhich door 22 strikes, 24 is a hasp plateformed withawidened head 25, flange 2 6, boss 27, in which isla slot 28 having a widened middle portion 29, and provided with integral bolts30 threaded forv engagement with nutsl3l onthe inner side of the door. 32 is ahasp consisting of a plate'portion 33 formed with apertures 34, shown as two in number, a curved shank 35-and anenlarged button" head 36, 37 is astriker plate formed with an aperture 38, a laterallyyprojecting guide member 39, rearwardly. projecting flanges 40, a laterally projecting flange 41 at the rear of one of flanges4'0, and integral bolts 42- projecting rearwardly from plates 37 and lug or flange 41. 43 is a detachable staple plate provided with apertures 44 eorresponding in number and position to bolts 42 on plate 37, and apertured staple 45,-piv- Voted depending lugs 46 having outwardly pro ecting members 47 each formed with an aperture 48, laterally projecting thumb pieces 49, stop 50 and rearwardly extending integral, bolt 51.

The operation of the device is as follows: Door 22 being slid to its closed position, hasp 32 is being first raised to their horizontal posi tion, shown in dotted lines Fig. 4. Lugs 46 are then allowed to drop to their normal position when apertures 48 in lugs 47 will register with asimilar aperture in staple 45,

so that the shackle of a seal or the hook portion of a padlock may be passed through all three'thereby securely sealing the car; It

will be noted that the integral bolts 30 on plate 24 pass through the door and arelsecured by nuts 31 on its inner side, so that ,there is no means of removing plate 24w'hen door 22 is closed. In door 22 is an aperture 52 adapted to be covered by plate 53 and to register with the slotted portion of plate24, which permits hasp 32 to be removed from or replaced in slot 28 without removing plate 24 from the car- This is advantageous because hasp 32, usually made of malleable passed over staple 45, lugs 46 iron, projects beyond plate 24 and is liable to-be broken with the rough treatment to which freight cars are subjected. A plate 53 is screwed to the inner side of end 25, so as to cover the rear face of boss 27 and prevent the accidental removal of hasp Hasp 32 swings vertically and horizontallv in the middle portion 29 of slot 28. It" is obvious that either of its apertures 34 may be engaged over staple 45, in one case, as shown, the door 22 in its tightly closed posi tion; or if the outer aperture 34 is used, the door is held slightly open. The guide member 39 on striker 37 serves to guide the door to its closed position and to reinforce it against'being forced outward. As shown in the drawing, door 22 slidesto the left to gain its closed position, and this is the ordinary construction. Staple plate 43 is engaged with striker 37 by. sliding its apertures 44 over the two rearwardly disposed. bolts 42 so'as to bringthe face of plate 43 against. therear face of striker portions 37, and so that plate 43 closes aperture 38 with'its parts 45-50 :projecting therebeyond. It will be noted that striker 37 and plate 43 are both provided with integral bolts which pass through the body of the car and are threaded for engage-c ment with nuts therein, staple plate 13 being additionally protected from removal from without by its ends being covered by striker plates 37. Y

Where a car door is closed'by sliding it to I the right, it is obvious that all the parts of that guide 39 serves the same function as bei the hasp portion.

plate 13 is adapted to engage with striker 37 our deviceexcept plate 13 are inverted, so

-fore, although it is below instead of above It is of course clear that when either in the position shown or in an inverted position.

The striker and hasp device shown respectively in Figs. 5 and 6 are similar to'those already described, except that bolts 42 and 51 are omitted, their place being supplied by bolt holes 121- and 511 respectively, so that ordinary bolts or screws may be used.

In the corresponding parts shown in Figs. 7 7 and 8, striker 54: is provided as before with vtion'to staple 58, plate .60 being adapted to cover plate 56 and being provided with lugs 46 as shown in F igzfl. It is obvious that both striker and plate may be secured to the car body as before, and that their functions are the same as that already described.)

Thestriker and plate of Figs. 9 and 10 are like those of Figs. 7 and 8, except that 'Gopies'of this patent may be obtained for 4:21 and 611 substituted'therefor.

bolts 41-2 and 61 are omitted and bolt holes It will, of course, be understood, that the omission of the integral bolts is a sacrifice of part of the advantages of our invention for the sake of economy.

Fig. 12 shows the'rear end of a bolt 63, which may be one of the bolts on' plate 2a or on one of the strikers or hasp plates shown.

It is shown as passed through wall 64: which may be either a door or body of a car. At

its inner end, bolt 63 is providedwith a transverse aperture 65 so positioned that'its rear portion extends beyond the innerface of wall 64w A wedge 66 is passed through aperture 65, driven as tight as possible and secured in place by a screw 67 passing. through a. small aperture 68 inthe end of the wedge. It is obvious that this method of f securing the bolt is an eflicient, and in some cases, an economical substitute for the threaded end and nutabove described.

Fig. 13 shows a somewhat similar device in which a number of bolts, as for instance, bolts 30 shown in Fig. .2, may be secured. In each bolt 70 is cut a transverse aperture as before, a single strap 71 passing through all these apertures and being secured by screws 72 on the inner face of door 22.

" It will be understood that various mechanical changes, other than those shown, may be made in our device without departing from the spirit of the invention; also that parts of the device maybe employed- 7 1 without the others.

Ourinvention is in some sense an improvement on an application filed May 15,

191 1; Serial Nll1l1ber 8387tl:5 by ourselves and A. Benjamin Appler; in that it provides, in some formsof construction," integral bolts so that the'exterior surfaces of the parts are solid and unbroken; in that itis adapted to right or left'running doors; in that it provides for the renewal of a broken hasp without the removal of the hasp fixture and in that it provides in Figs; 12 and 13 for a novel method of securing the bolts in place. e
